config NFCT_PINS_AS_GPIOS
bool "NFCT pins as GPIOs"
depends on HAS_HW_NRF_NFCT
help
Two pins are usually reserved for NFC in SoCs that implement the
NFCT peripheral. This option switches them to normal GPIO mode.
HW enabling happens once in the device lifetime, during the first
system startup. Disabling this option will not switch back these
pins to NFCT mode. Doing this requires UICR erase prior to
flashing device using the image which has this option disabled.
NFC pins in nRF52 series: P0.09 and P0.10
NFC pins in nRF5340: P0.02 and P0.03

Specifies how the SystemInit() function should handle the APPROTECT
mechanism.
config NRF_APPROTECT_USE_UICR
bool "Use UICR"
help
When this option is selected, the SystemInit() function loads the
firmware branch state of the APPROTECT mechanism from UICR, so if
UICR->APPROTECT is disabled, CTRLAP->APPROTECT will be disabled.
config NRF_APPROTECT_LOCK

help
When this option is selected, the SystemInit() function locks
the firmware branch of the APPROTECT mechanism, preventing it
from being opened.
config NRF_APPROTECT_USER_HANDLING
bool "Allow user handling"
depends on !SOC_SERIES_NRF52X
help
When this option is selected, the SystemInit() function does not
touch the APPROTECT mechanism, allowing the user code to handle it
at later stages, for example, to implement authenticated debug.
